What value does crypto provide to those groups you mentioned, that cash cannot provide? If the answer is, it allows them to break laws then yes by definition they are criminals. You can argue that some of these laws are unjust, sure but that's tangential to the question. The value of crypto by volume is largely for speculative bets and criminal activities.
And dissidents and marginalized communities and activists and anyone living in an oppressive state.
Are you really trying to argue that anonymity is only valuable to criminals?
